Step-by-step explanation:
You multiply the 5.5 pounds by the 80 cents then multiply the awnser of that by .25 and subtract that from the awnser of 5.5*.80
-- A "mixed number" is (a whole number) plus (a fraction).
-- Two mixed numbers = (two whole numbers) and (two fractions).
-- The smallest whole number is ' 1', so when you add up all of that,
the smallest possible sum is (2) plus (two fractions).
-- So the sum must always be greater than 2 .
============================================
<em>THAT'S IF BOTH MIXED NUMBERS ARE POSITIVE </em>.
<em>If one of them is negative</em>, then it's easy to do:
(3 and 1/2) + negative (1 and 1/2) = <u>2</u>
(25 and 7/10) + negative (23 and 7/10) = <u>2</u>
Answer:
Interest She'll make in a year is $30.10125
Step-by-step explanation:
Interest = PRT ÷ 100
Principal = $523.50
Rate = 5³/₄% = 5.75%
Time= 1year
Interest I = (523.50 × 5.75 × 1) ÷ 100 = $30.10125
Interest She'll make in a year is $30.10125
